Add Registry20 GUID management and DPAPI support

Introduce tools and UI to read, write, backup and restore QQ Registry20 GUIDs using Windows DPAPI. Adds a Python CLI (guid_tool.py) for local Registry20 operations and a new TypeScript package napcat-dpapi with native bindings for DPAPI. Implements Registry20Utils in the webui-backend to protect/unprotect Registry20, plus backup/restore/delete helpers. Exposes new backend API handlers and routes (get/set GUID, backups, restore, reset, restart) and integrates frontend GUIDManager component and qq_manager controller methods. Propagates QQ data path via WebUiDataRuntime (setter/getter) and wires it up in framework/shell; updates Vite alias and package.json to include the new dpapi workspace. Includes native addon binaries for win32 x64/arm64 and basic tsconfig/readme/license for the new package.
